IMPROVEMENT IN THE MACHINE FOR SPREADING LIME, ASHES, MARL, PLASTER, OROTHER FlilABLE MANURES.

' Specification forming part of Letters Patent No. 258, dated July 5,1837. v

To all whom it may concern:

Be it known that I, FRANCIS H. SMITH, of the city of Baltimore and Stateof Maryland, haveinveuted a new and useful Machine for Spreading Lime,Ashes, Marl, Plaster, and other Friable Manure; and I do hereby declarethat the following is a full and exact description.

A A inthe accompanying drawings represent a common cart-body, with ahopper, as at b, in the bottom, about twelve inches behind the axle, theopening about ten inches wide and reaching across the entire Width ofthe cart-bottom. Beneath this hopperis a revolving fluted metalcylinder, 0. about five inches diameter, the tongues of which projectabout three-fourths of an inch. As this cylinder re volves the manuiefalls into the interstices or cavities between the tongues, and iscarried down out against a smooth metal cylinder, d, about three andonc-halfinches diameter,which lies parallel and on the same level withthe first. The machinery is put in operation by the motion or advancingof the cart.

The same letters in theseveral figures in the drawings represent thesame parts.

Figure 2-is an end view of the machinery. e is a driving cog-wheel onone hub of the cart'wheel. It gears into the cog wheel f. This cog-wheelturns on a pin-journal attached to the cart-body. 0n the same journal isthe cog-wheel g, which may turn iudependentlyof f when no spreading isrequired, but it is made to revolve with'f by being locked with f by hpassing through the arms of both wheels. The wheel 9 gears into thecog-wheel t, which is on the end of the journal of the cylinder 0. Thedotted lines represent the cylinders, as O (l G d, and the spring 0, tobe hcreinat'ter described. If the small wheel 11 and the larger one, g,are made to exchange places, the speed ot'the cylinder is reduced, andconsequently the quantity of manure distributed is diminished; and inlike manner, by means of two or more pairs of wheels, each pair ofdifferent relative sizes, but all fitting on the samejournals, anyrequired quantity may be had.

Fig. 3 represents an end view of the method of placing or hanging thecylinders. j is the false bed bolted to the cart-sill, to which themetal seats and caps k and l are attached. at is an open or long restfor the journals of the cylinder 07. When the manure is carried down -inthe direction of the arrow the cylinder d is cylinders to crush orpulverize lime, calcined shells, or other friable substances.

When describing the cylinder 0, for the sake of perspicuity, l simplytermed it a fluted metal cylinder, but I can'adopt any suitable materialor any form in the distributing'surface of the cylinder. The tongues maybe straight, spiral, and continuous, or broken into compartments ofvarious forms and dimensions. I can in like manner vary the form of thefollower n1 yielding cylinder 0!, the relative place of the machinery,or, instead of coggearing, the motion may be communicated trom the hubof the cart-wheel by achain or band and pulley on the cylinder (J.

What I claim as my invention, and desire to secure by Letters Patent, is

1. The fluted cylinder 0, or a revolving cylinder having receptacles orcavities to receive the manure to be thrown out as it revolves, incombination with the cylinder (7.

2. The cylinder (1 as applied in front of O to relieve and facilitate Oin its revolution with the springs, allowing it to recerle and stillrevolve. v

3. The application of the cog-gearing, as described above, and the modeof regulating the quantity by difi'erent pairs of wheels working andfitting on the same centers.
